Patent DE-3902536-A1 (DE)
Inventor: TATAS RALF DR
IPC: C09D151/00
Filed: 1989-01-28
Abstract: Sterically stabilised aqueous polymer dispersions, based on radically polymerised ethylenically unsaturated monomers and on a graft polymer used as a protective colloid, are produced by radically grafting the essentially hydrophobic ethylenically unsaturated monomers, such as alkylesters of acrylic or methacrylic acid, on the essentially water-soluble or water-dispersable polymeric protective-colloid preproduct by means of a graft initiator, and by polymerising, in the presence of the protective colloid thus obtained, radically polymerisable ethylenically unsaturated monomers in an aqueous medium by emulsion polymerisation in the presence of a usual initiator forming free radicals. The protective colloid preproducts are preferably polysaccharides and polymerisates of ethylenically unsaturated monomers, in particular polyvinylpyrrolidon and polyvinylalcohol. These aqueous polymer dispersions, which can be processed even at room temperature, are a suitable base for varnishes and coatings.

Patent DE-3920489-A1 (DE)
Inventor: UNGER HANS
IPC: B60T13/26
Filed: 1989-06-22
Abstract: In the case of such an air drier a connectable regenerating device is assigned to a drying cartridge (3) containing a drying agent (7); by means of this the drying agent located in the drying cartridge (3) is regenerated, that is by means of the compressed air from the compressed air system the damp drying agent is passed through and the bound water extracted from this before it passes out into the open air preferably via a ring filter and an exhaust valve. The regenerating device has a timed switch which can be switched on by the control pressure of a pressure regulator preferably incorporated on the device in order to initiate regeneration at pre-determined time intervals. The switch (45) contains a piston (43) to which compressed air can be admitted when the control pressure of the pressure regulator is reached, which piston, as a function of a link motion in predetermined stages and by means of a valve plunger (59) opens a connection which allows the compressed air to flow back out of the compressed air system through the drying agent (7) in the drying cartridge (3). The piston (43) acts in concert with a connecting member rotatable according to the piston movement, which member in a predetermined angular position carries the valve plunger (59) with it, thereby opening the connection for initiation of the regeneration. <IMAGE>
